Abstract: A syringe containing a high water content product and for use in a drug infusion system is provided. The syringe includes a plunger carrying front and rear o-rings made of a diene rubber compound such as chlorobutyl rubber or bromobutyl rubber to impart very low gas permeability characteristics to the o-rings. The plunger may be molded as a single part or in two parts. If molded as one part with radially-engaging mold portions, the seal glands in the plunger may include parting lines from the mold. If molded as two parts with axially-engaging mold portions, the front seal gland may include a sealing surface and under cut that has no parting line. The o-rings may be surface treated with a lubricant to improve sealing where the molding process gives rise to parting lines in the seal glands, which can result in leak paths on the ID of the o-rings. The o-rings provide a gas-tight sliding seal that can withstand temperature changes from ?25° C. to 40° C.

Abstract: A tray is provided for retaining a plurality of food items that includes a bottom wall portion and a sidewall portion together defining a plurality of compartments separated from each other by dividers and each configured to retain a stack of the food items. Each of the dividers is interconnected to the sidewall portion by a pair of scalloped ledges. The sidewall portion of the tray includes two side panels each including stiffening ribs extending only along a portion thereof, but not extending along an entire length thereof. The tray is configured such that, in response to a compressing force applied to the tray in a direction substantially perpendicular to the first and second side panels, the sidewall portion of the tray deflects in a direction away from the food items.

Abstract: A tray (100) is provided for retaining a plurality of food items (90) that includes a bottom wall portion (120,122,124) and a sidewall portion (126, 128, 130, 132, 134,136, 138, 140, 142, 144, 146, 148) together defining a plurality of compartments (114, 116, 118) separated from each other by dividers (152, 154) and each configured to retain a stack of the food items (90). Each of the dividers (152, 154) is interconnected to the sidewall portion by a pair of scalloped ledges (172, 174, 176, 178). The sidewall portion of the tray includes two side panels (138, 148) each including stiffening ribs (156) extending only along a portion thereof, but not extending along an entire length thereof.

Abstract: A syringe containing a high water content product and for use in a drug infusion system is provided. The syringe includes a plunger carrying front and rear o-rings made of a diene rubber compound such as chlorobutyl rubber or bromobutyl rubber to impart very low gas permeability characteristics to the o-rings. The plunger may be molded as a single part or in two parts. If molded as one part with radially-engaging mold portions, the seal glands in the plunger may include parting lines from the mold. If molded as two parts with axially-engaging mold portions, the front seal gland may include a sealing surface and under cut that has no parting line. The orings may be surface treated with a lubricant to improve sealing where the molding process gives rise to parting lines in the seal glands.
